2015-10-28IB/srp: Convert to new registration APISagi Grimberg
Instead of constructing a page list, call ib_map_mr_sg and post a new ib_reg_wr. srp_map_finish_fr now returns the number of sg elements registered. Remove srp_finish_mapping since no one is calling it.

2015-10-28IB/srp: Split srp_map_sgSagi Grimberg
This is a preparation patch for the new registration API conversion. It splits srp_map_sg per registration strategy (srp_map_sg[fmr|fr|dma]. On its own it adds some code duplication, but it makes the API switch easier to comprehend.

2015-10-28IB/core: Introduce new fast registration APISagi Grimberg
The new fast registration verb ib_map_mr_sg receives a scatterlist and converts it to a page list under the verbs API thus hiding the specific HW mapping details away from the consumer. The provider drivers are provided with a generic helper ib_sg_to_pages that converts a scatterlist into a vector of page addresses. The drivers can still perform any HW specific page address setting by passing a set_page function pointer which will be invoked for each page address. This allows drivers to avoid keeping a shadow page vectors and convert them to HW specific translations by doing extra copies. This API will allow ULPs to remove the duplicated code of constructing a page vector from a given sg list. The send work request ib_reg_wr also shrinks as it will contain only mr, key and access flags in addition.
